Game controller

A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is usually connected to a game console or computer by means of a wire or cord, although, since the mid-2000s, wireless controllers have become widespread. Input devices that have been classified as game controllers include keyboards, mice, gamepads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers.

Game controllers have been designed and improved over the years to be as user friendly as possible. The Microsoft Xbox controller, with its shoulder triggers that mimic actual triggers such as those found on guns, has become popular for shooting games.[1] Some controllers are designed to be deliberately best for one type of game, such as steering wheels for driving games, or dance pads for dancing games.

A gamepad, also known as a joypad, is held in both hands with thumbs and fingers used to provide input. Gamepads can have a number of action buttons combined with one or more omnidirectional control sticks or buttons. Action buttons are generally handled with the digits on the right hand, and the directional input handled with the left. Gamepads are the primary means of input on most modern video game consoles. Due to the ease of use and user-friendly nature of gamepads, they have spread from their origin on traditional consoles to computers, where a variety of games and emulators support their input as a replacement for keyboard and mouse input.[3] Most modern game controllers are a variation of a standard gamepad. Common additions include shoulder buttons placed along the edges of the pad, centrally placed buttons labeled start, select, and mode, and an internal motor to provide haptic feedback.

A paddle is a controller that features a round wheel and one or more fire buttons. The wheel is typically used to control movement of the player or of an object along one axis of the video screen. Paddle controllers were the first analog controllers and they lost popularity when "paddle and ball" type games fell out of favor. A variation, the Atari driving controller, appeared on the Atari 2600. Designed specifically for the game Indy 500, it functioned almost identically in operation and design to the regular paddle controller. The exceptions were that its wheel can be continuously rotated in either direction, and it was missing the extra paddle included on the previous model. Unlike a spinner, friction prevented the wheel from gaining momentum.

A joystick is a peripheral that consists of a handheld stick that can be tilted around either of two axes and (sometimes) twisted around a third. The joystick is often used for flight simulators. HOTAS controllers, composed of a joystick and throttle quadrant (see below) are a popular combination for flight simulation among its most fanatic devotees. Most joysticks are designed to be operated with the user's primary hand (e.g. with the right hand of a right-handed person), with the base either held in the opposite hand or mounted on a desk. Arcade controllers are typically joysticks featuring a shaft that has a ball or drop-shaped handle, and one or more buttons for in game actions. Generally the layout has the joystick on the left, and the buttons on the right, although there are instances when this is reversed.

A trackball is basically an upside-down mouse that is manipulated with the palm of one's hand. It has the advantage of not requiring a lot of desktop space, and that it is as fast as one can roll the ball on it. This is faster than one can move a mouse due to space not being an issue. It was a precursor to the mouse. Notable uses of a Trackball as a gaming controller would be games such as Centipede, Marble Madness, Golden Tee Golf and SegaSonic the Hedgehog.

A throttle quadrant is a set of one or more levers that are most often used to simulate throttles or other similar controls in a real vehicle, particularly an aircraft. Throttle quadrants are most popular in conjunction with joysticks or yokes used in flight simulation.

A yoke is very similar to a steering wheel except that it resembles the control yoke found on many aircraft and has two axes of movement: not only rotational movement about the shaft of the yoke, but also a forward-and-backward axis equivalent to that of pitch control on the yoke of an aircraft. Some yokes have additional controls attached directly to the yoke for simulation of aircraft functions such as radio push-to-talk buttons. Yokes, like throttle quadrants and pedals, are popular with serious flight-simulation enthusiasts.

Pedals may be used for driving simulations or flight simulations. In the former case, an asymmetric set of pedals can simulate accelerator, brake, and clutch pedals in a real automobile. In the latter case, a symmetric set of pedals simulates rudder controls and toe brakes in an aircraft. As mentioned, most steering wheel controllers come with a set of pedals.

A computer keyboard and mouse are typical input devices for a personal computer and are currently the main game controllers for computer games. The mouse is often used with a mousepad to achieve greater speed, comfort, accuracy and smoother movement for the gamer. Some video game consoles also have the ability to function with a keyboard and a mouse. The computer keyboard is modelled after the typewriter keyboard and was designed for the input of written text. A mouse is a handheld pointing device used in addition to the keyboard. For games, the keyboard typically controls movement of the character while the mouse is used to control the game camera or used for aiming. While originally designed for general computer input, there are several keyboard and mouse peripherals available which are designed specifically for gaming, often with gaming-specific functions built-in. Examples include peripherals by Razer, the "Zboard" range of keyboards and Logitech's 'G' series. The numeric keypad found on the keyboard is also used as a game controller and can be found on a number of separate devices, most notably early consoles, usually attached to a joystick or a paddle. The keypad is a small grid of keys with at least the digits 0-9. A Gaming keypad is a specialized controller used for FPSs, RTSs and some arcade type games. These controllers can be programmed to allow the emulation of keys, and macros in some cases. These generally resemble a small part of a keyboard but may also feature other inputs such as analog sticks. They were developed because some of these games require a keyboard to play, and some players find this to be awkward for such a task.

A touchscreen is an input device that allows the user to interact with the computer by touching the display screen. The first attempt at a handheld game console with touchscreen controls was Sega's intended successor to the Game Gear, though the device was ultimately shelved and never released due to the high cost of touchscreen technology in the early 1990s.[5] The first released console to use a touchscreen was the Tigergame.com in 1997. Nintendo popularized it for use in video games with the Nintendo DS and Nintendo 3DS; other systems including the Tapwave Zodiac as well as Smartphones and the vast majority of PDAs have also included this feature. The primary controller for Nintendo's Wii U console, the Wii U GamePad, features an embedded touchscreen. Modern touch screens use a thin, durable, transparent plastic sheet overlaid onto a glass screen. The location of a touch is calculated from the capacitance for the X and Y axes, which varies based upon where the sheet is touched. One console that is touchscreen, but is not manufactured by Nintendo is Sony's PlayStation Vita which has a 5 inch OLED touchscreen.

Breathing controllers help their users improve breathing through video games. All controllers have sensors that sense users breath, with which user controls video game on computer, tablet or on smartphone. Alvio is a breathing trainer, symptom tracker and mobile game controller.[6] Zenytime promotes deep, rhythmic breathing to trigger shot-term rewards of controlled breathing (relaxation, improved oxygenation...).[7] Breathing games by Breathing Labs are based on Pursed lip breathing and are used on iPhone / iPad, Windows, OS X and Android devices.[8]

Motion controllers include the Sega Activator, released in 1993 for the Mega Drive (Genesis). Based on the Light Harp invented by Assaf Gurner,[9] it could read the player's physical movements and was the first controller to allow full-body motion sensing. However, it was a commercial failure due to its "unwieldiness and inaccuracy".[10] Nintendo's Wii system released in 2006 utilizes the Wii Remote controller, which uses accelerometers to detect its approximate orientation and acceleration and an image sensor,[11] so it can be used as a pointing device. The Sixaxis, DualShock 3, and PlayStation Move controllers for Sony's PlayStation 3 system have similar motion sensing capabilities. In 2010, Microsoft released the Kinect for the Xbox 360. This motion sensing controller uses cameras to track a players movement. Microsoft released a revised version of the Kinect with the launch of the Xbox One. This controller was bundled with the console on launch, and was removed from the default bundle in June 2014. Sony's EyeToy similarly uses cameras to detect the player's motions and translate them into inputs for the game.

Pinball controllers and multi-button consoles for strategy games were released in the past, but their popularity was limited to hardcore fans of the genre.

Dance pads, essentially a grid of flat pressure-sensitive gamepad buttons set on a mat meant to be stepped on, have seen niche success with the popularity of rhythm games like Dance Dance Revolution and Pump It Up. The dance pad was first introduced by Bandai on the Famicom in 1986 as a part of their "Family Fun Fitness" set, then Exus released the "Foot Craz" pad for the Atari 2600 in 1987. Nintendo purchased the technology from Bandai in 1988 and used it on their "Power Pad", for the Famicom and NES.

Balance board: The Wii Balance Board comes with the game Wii Fit. Several other game are in development which will be compatible with the balance board. This was preceded by decades by the Joyboard, made to plug into an Atari 2600, to play skiing and surfing games.

Buzzers: A recent example of specialized, while very simple, game controllers, is the four large "buzzers" (round buttons) supplied with the PlayStation 2 and PlayStation 3 quiz show game series Buzz! (2005–present); both game and controllers clearly being inspired by the television show genre.

NeGcon: is a unique controller for racing games on the PlayStation. Physically it resembles a gamepad, but its left and right halves twist relative to each other, making it a variation of the paddle controller.

Steel Battalion for the Xbox was bundled with a full dashboard, with 2 joysticks and over 30 buttons, in an attempt to make it feel like an actual mecha simulator.

Fishing rod: the first fishing rod controller appeared as an accessory for the Dreamcast video console for playing Sega Marine Fishing. Later other games for PlayStation console use also a similar controllers.

Optical motion tracking systems such as TrackIR and FreeTrack use a video camera to track an infrared illuminated or emissive headpiece. Small head movements are tracked and then translated into much larger virtual in-game movements, allowing hands-free view control and improved immersiveness.

Mechanical motion tracking systems like Gametrak use cables attached to gloves for tracking position of physical elements in three-dimensional space in real time. The Gametrak mechanism contains a retracting cable reel and a small tubular guide arm from which the cable passes out. The guide arm is articulated in a ball joint such that the arm and ball follow the angle at which the cable extends from the mechanism. The distance of the tracked element from the mechanism is determined through components which measure the rotation of the spool drum for the retracting cable reel, and calculating how far the cable is extended.

Exoskeleton controllers use exoskeleton technology to provide the player with different responses based on the player’s body position, speed of movement, and other sensed data. In addition to audio and visual responses, an exoskeleton controller may provide a controlled resistance to movement and other stimuli to provide realism to the action. This not only lets players feel as if they are actually performing the function, but also helps reinforce the correct muscle pattern for the activity being simulated. The Forcetek XIO is an example of an exoskeleton video game controller.

Instrument panels are simulated aircraft instrument panels, either generic or specific to a real aircraft, that are used in place of the keyboard to send commands to a flight simulation program. Some of these are far more expensive than all the rest of a computer system combined. The panels usually only simulate switches, buttons, and controls, rather than output instrument displays.

Train controls: Other instrument panel like hardware such as train controls have been produced. The "RailDriver"[16] for example is designed to work with Trainz, Microsoft Train Simulator and Kuju Rail Simulator. (as of January 2009) it is limited in ease of use by the lack of a Windows API interface for some of the software it is designed to work with. A train controller for a Taito bullet train sim has also been made for the Wii console.[17]
